We look at the division of 938471 by 86 
We want to divide 938471 by 86.

Moving on to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 86

On to step 2:
If we divide 93 by 86, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 93 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 86

Step 3:
86 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 78 to get 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 86

Moving on to step 4:
784 divided by 86 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 774 from 784, we get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 86

Going ahead to step 5:
107 divided by 86 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1091.0
Deduct 86 from 107 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 86

Step 6:
When dividing 211 by 86, we get 2 with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 10912.0
Deduct 172 from 211 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 86 fits into 390 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 10912.4
If we take 344 away from 390, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 10912.45
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 10912.453
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 86 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 10912.4534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 10912.45348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 10912.453488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 10912.453488 with a remainder of 3.2e-06.
